The apartment walls were plastered with Li Chenzhou's schedules, red markings glaring like bloodstains. Lin Qiao traced one with her finger—**Next Tuesday, 15:00, routine inspection of the underground lab at the old estate.**
"Know why I chose you?" Li Yunzheng retrieved a pocket watch from the safe, its lid concealing a microchip. **"MN-07's original data is here. It requires twin gene resonance to unlock."**
Beneath the glass panel of the nightstand lay a yellowed newspaper clipping of Lin Qiao's college debate competition. The date read **November 2009**—eight years before their so-called "first meeting."
**"You've been watching me."**
"No." He suddenly seized her wrist and pressed it against his chest. **"It's remembered here."**
A button popped loose, revealing a surgical scar over his left breast. Her fingertips brushed against an unnatural rhythm—the metallic edge of a pacemaker.
**"At twenty, Li Chenzhou replaced my heart with a machine."** His smile twisted. **"All because I sneaked out to see your graduation ceremony."**
Lightning split the sky outside, illuminating the open copy of *Wuthering Heights* on the desk. A corner was folded on page 134—Heathcliff's line: **"I love my murderer—but yours! How can I?"**
